45 Claims. (01. 16486) This invention relates primarily to machines for punching holes in insoles, but it will be understood that as to some of its novel features it is not limited in utility to machines for performing operations of that particular character or to machines for operating on that particular kind of work.

An immediate object of the invention is to pro vide a machine for punching in insoles holes to be used in positioning shoes in shoe machines in accordance with a method claimed in a copending application of mine, Serial No. 395,037, filed on May 24, 1941. To insure that the positions of the shoes in such shoe machines will not be afiected by variations in the positions of the insoles on their lasts, it is preferable to punch the holes in the insoles with the insoles mounted on the lasts and held in fixed relation thereto, and the present invention, in one aspect, accordingly provides a machine for this purpose, the machine herein shown having a pair of punches which punch corresponding holes in the forepart of each insole in accurately predetermined locations farther inwardly from the edge of the insole than the margin of the upper extends when in lasted position. For the sake of special accu racy in positioning shoes in machines which operate on the uppers, such as toe-lasting machines, it is also preferable that the locations of the holes in the insole be determined by reference to the outer face of an upper also mounted on the last and, it may be, partially shaped over the last. Accordingly, the machine herein shown is provided with gage mechanism which by engagement with the outer face of the upper, if there is an upper on the last, positions the last and its shoe materials, herein frequently referred to inclusively as the shoe, lengthwise, laterally and angularly for the insole-punching operation, the term angularly being used herein with reference to orientation of the shoe about an axis extending heightwise thereof. In the construction shown the punches act on the insole in response to heightwise movement of the shoe efiected by a toe rest which engages the shoe at the top of the forepart, the movement of the shoe being limited by stop mechanism comprising a shoe rest member engaged by the insole and mounted for limited movement in response to the pressure of the insole thereon. Preferably, as

illustrated, the punches are solid punches having conical insole-engaging ends; and by reason of the shape of the punches, the character of the force applied in the insole-punching operation and the fact that the movement of the shoe is limited as above explained, the punches penetrate only part way through the insole, so that the holes are not visible on the inner face of the insole.

The above-mentioned gage mechanism, in the machine herein shown, comprises a toe-end gage which determines the position of the shoe lengthwise and against which the operator presses the toe-end face of the shoe in presenting the shoe to the machine, and opposite side gages which by engagement with the sides of the shoe determine its position laterally and angularly. To facilitate the presentation of the shoe to the machine and to avoid any danger of injuring the upper by frictional action of the side gages th'ereon if there is an upper on the last, the invention further provides a construction whereby the side gages are moved toward each other to position and clamp the shoe by power-operated means after the shoe has been presented against the toe-end gage, this power-operated means being started in operation .by the pressure of the shoe against the toe-end gage. More particularly, in the construction shown, the side gages are moved into their operative positions by fluid-operated means, and fluid is admitted to this fluid-operated means by a valve which is operated by electrical means energized by the movement of the toe-end gage. In accordance with a further characteristic of the illustrative embodiment of the invention the toe rest which moves the shoe to render the punches effective on the insole is operated by additional fluid-operated means controlled by the means which operates the side gages in the manner above described. The power operation of the whole machine is thus responsive to electrical control through the pressure of the shoe on the toe-end gage. In response to the movement of the shoe by the toe rest in the insole-punching operation the electrical control of the machine is terminated, whereupon the parts are returned by springs or by gravity to their starting positions.

The above and other features of the invention, including novel means for controlling the punches in such manner as to equalize the forces which they apply to the work while permitting them to adjust themselves to the contour of the work, novel side gage mechanism, and various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

Fig. 8 is a view similar to Fig. 3, but with parts omitted and with the parts which are visible positioned as they are in Fig. 6.

The machine is provided with a column 2 adapted to rest on the floor, and secured to this column is an upwardly extending frame plate 4. Fast on the plate 4 is a casting 6 to which are secured a pair of upwardly extending rods 8, and secured to the upper ends of these rods is a crossbar In which serves as a support for a rearwardly extending block l2. Slidingly mounted for vertical movements in the crossbar H] are 'two punches 14 having pointed lower ends of conical shape arranged to punch holes part way through the insole a of a shoe on its last when the shoe is forced upwardly against the punches by means hereinafter described. Each of the punches I4 is provided with an enlarged cylindrical head I6 slidingly movable in a bore in the crossbar l0 and controlled by a light spring l8 which tends to force the punch upwardly. The two heads l6 are engaged above by the opposite end portions of an equalizing lever 20 which is fulcrumed midway between its opposite ends on a sleeve 22 surrounding a screw 24, this being one of two screws for securing the block l2 to the crossbar ID. The heads l6 are located at equal distances from the fulcrum of the lever. It will be understood that through the lever 26 the forces applied by the two punches [4 to the insole are substantially equalized while the punches are permitted to adjust themselves to the contour of the bottom of the last, so that they are forced substantially equal distances into the insole.

Mounted for vertical movement in the block I2 is the stem 26 of a shoe rest member 28 arranged to engage the bottom face of the extreme toe end of the insole when the shoe is initially presented to the machine, as illustrated diagrammatically in Fig. 1. In engagement with the upper end of the stem 26 is a spring 36 which tends to force 40 threaded in the frame plate 4. A spring 4| holds the end gage initially in contact with the rear face of the block l2. The position of the shoe laterally and angularly relatively to the punches I4 is determined by two pairs of side gages 42 and 44 (Fig. 3) which are in the nature of bell-crank levers and are mounted on vertical shafts 46 rotatable in brackets 48 and 56 fast on the frame plate 4. The two gages 42 are arranged to act on the shoe at the opposite sides of the forepart in the vicinity of its ball portion and are connected together by gear segments 52 (Fig. 3) so that their movements toward or from each other widthwise of the shoe are equalized. The two gages 42 are supported on the bracket 48, the left-hand gage being secured by a set screw 54 to the shaft 46 on which it is mounted and the right-hand gage being loosely mounted on the other shaft 46. The two gages 44 are arranged to act on the shoe at the opposite sides of its toe portion and are connected together for equal movements toward or from each other by gear segments 56. The'gages 44 are supported on the gages 42, the right-hand gage being secured by a set screw 58 to its shaft 46 and the left-hand gage being loose on the other shaft. It will thus be seen that one pair of gages are movable'by one of the shafts 46 and the other pair by the other shaft. A' spring 66 connected to pins on the two shafts tends to turn the shaftsin directions to retract the gages from the sides of the shoe and maintains them initially in positions determined by a stop pin 62 which extends upwardly from the bracket 43. In order to guard against any marking of the shoe upper by pressure of the side gages thereon, a flexible strap 64 which may be made of leatheris connected to the two gages 42 and 44 at each side of the shoe in position to contact with the upper when the gages are swung inwardly toward the shoe. One end of each strap is fast on a plate 66 pivotally mounted on a pin 68 on the gage 42, and the other end of the strap is fast on a pin 10 extending downwardly from the gage 44 in fixed relation thereto.

Fast on each shaft 46 above the bracket 56 is an arm 12, and loosely mounted on each shaft below the bracket is an arm 14 supported by a washer 15 on the lower end of the shaft. Associated with each pair of arms 12 and I4 is a compression spring 16 one end of which abuts against a block 18 (Fig. swiveled to turn about a vertical axis on the arm 12 and the other end of which abuts against a block swiveled to turn about a vertical axis on the arm 14. Extending through both these blocks and the spring is a rod 82 (Fig. 4) provided with a head 84 for engaging the block 18 and with a nut 86 for engaging the block 80. It will thus be seen that swinging movement may be imparted yieldingly to the arm 12 through the spring I6 by movement of the arm 14. Swinging movements of both arms 14 to move the gages 42 and 44 toward the shoe into their operative positions are effected by a bell-crank lever 88 (Fig. 1) which is pivotally mounted on a bracket 90 fast on the I frame plate 4 and has an upwardly extending tioning the shoe heightwise with the insole curved arm 92 arranged to engage the arms 14 as illustrated in Fig. 4. A rearwardly extending arm 94 of the bell-crank lever 88 has depending therefrom a rod 96 the lower end of which is connected to a lever 98 pivotally mounted at its front end on a bracket I00 fast on the column 2. The rear end of the lever 98 is pivotally con nected to a link 102 which is connected at its up per end to a piston I04 movably mounted in a cylinder I06. This cylinder is supported at its upper end by a pin I08 on a bracket I I fast on a plate II2 which is secured to the bracket I00. It will thus be seen that in response to downward movement of the piston I04 the bell-crank lever 88 is operated to swing the two arms 14 (Fig. 4) in opposite directions, respectively, and thus to impart to the side gages 42, 44 their shoe-positioning and clamping movements, each of the springs 16 yielding as required when the pair of gages 42 or 44 controlled thereby are stopped by the resistance of the shoe to their further move ments. Downward movement of the piston I94 is limited by engagement of the lower end of the link I02 with a screw II4 threaded in a lug on the plate I I2.

The piston I04 is preferably operated by compressed air which may be obtained from a source of factory supply if such is available or may be supplied by a suitable pump. As illustrated, a pipe II6 leads from the source of supply and communicates with apipe I I8 which extends rearwardly and then toward the left to valve mechanism I20 from which a pipe I22 leads to the upper end of the cylinder I06. The valve mechanism I20 (Fig. 2) comprises a tube I24 which is clamped between a boss I26 on the plate H2 and a bar I28 secured to this plate. The tube I24 is divided between its opposite ends by a partition I30, and its opposite ends are in communication, respectively, with the pipe II8 and the pipe I22. Extending through the tube at the opposite sides respectively, of the partition I39 are two sets of ports I32 and I34. Slidingly mounted on the tube is a sleeve valve I36 provided with an annular chamber I38. When the valve is in the position illustrated in Fig. 2 the ports I32 lead ing from. the pipe II8 are closed and the ports I34 leading from the pipe I22 are open to exhaust. Movement of the valve toward the left from that position serves to establish communication between the ports I32 and I34, so that compressed air is admitted to the cylinder I98 to operate the piston I04. The valve is controlled by a lever I40 which is pivotally mounted between its opposite end on a member I42 secured to the plate H2 and is provided at its upper end with a pin I44 extending into an annular groove I46 in the valve. A spring I48 connected to the pin I 44 holds the valve initially in its idle position against the boss I26, as illustrated in Fig. 2.

To move the valve I38 into position to admit compressed air to the cylinder I 06 the lever I40 is operated by electrical means comprising a solenoid I50 arranged to act on a plunger 12 connected by a link I54 .to the lower end of the lever. Current is supp-lied to the solenoid from any suitable source through wires I50 which lead to a switch I58 (Fig. I) mounted in a casing I60 fast on a bracket I62 secured to the bracket 48. The switch I58 is closed to cause current to flow through the solenoid I58 by rearward movement of a plunger I64 against the resistance of a spring I66. Such movement of the plunger is efiected by rearward swinging movement of the toe-end gage 36 in response to the pressure of the shoe thereon when the operator presents t..e shoe to the machine. For this purpose there is pivotally mounted on the gage a pawl I88 the rear end of which is normally positioned opposite the front end of the plunger I64, as shown in Fig. 1, and the front end of which extends into a recess I formed in the stem 26. A spring-pressed pin I12 in the gage 36 tends to lift the rear end of the pawl I68 and holds it normally in the position in which it is shown in Fig. 1.

In the machine herein shown the operation of the punches I4 to punch the holes in the insole results from upward movement of the shoe relatively to the punches. For thus moving the shoe there is provided a toe rest I14 mounted on the upper end of a plunger or piston I16 which is vertically movable in a bore in the casting 6, this casting being so formed as to provide a cylinder I18 for the piston. Compressed air is admitted to the lower end of the cylinder I18 from the supply pipe II6 through a pipe I and valve mechanism I82 which is similar to the previously described valve mechanism I20. Briefly, this valve mechanism comprises a tube I84 clamped between a bar I86 and a nipple I88 at the lower end of the cylinder I18, the upper end of the tube communicating with the cylinder and the lower end with the pipe I60. The tube is divided by a partition I90 extending between two sets of ports I92 and I94. Movable on the tube is a sleeve valve I96 which in its normal position in engagement with the bar I86 closes the ports I94 and opens the ports I92 to exhaust. The valve is moved upwardly to establish communication between the two sets of ports and thus to admit compressed air to the cylinder I18 by a lever I98 provided with a pin 200 which extends into an annular groove 202 in the valve, the lever being pivotally mounted between its ends on a pin 204 supported on a block 206 fast on the frame plate 4. The rear end of the lever I38 is pivotally connected to a block 288 which is slidingly mounted on the rod 96 and rests normally against a collar 2I0 fast on the rod. Between this block and another collar 2I2 also fast on the rod is a compression spring 2l4. It will thus be seen that the movement of the lever I98 to operate the valve I96 in the manner above described is derived from the downward movement of the rod 96 effected by the piston I84. The lever I98, however, is initially held against such valveoperating movement by a latch 2I6 pivotally mounted on the block 206 and held by a spring 2I8 in a notch 220 in the lever. Accordingly, the spring 2I4 is compressed by the downward movement of the rod 96 until the side gages 42 and 44 have been moved into positions to clamp the shoe. Thereafter, as the rod continues its downward movement, the latch 2 I 6 is withdrawn from the notch 220 by a collar 222 which is fast on the rod 96 and has a conical face 224 arranged to engage a pin 226- carried by the latch. The spring 2I-4 then expands and operates the lever I98 to move the valve I96 into position to admit compressed air to the cylinder I18, whereupon the toe rest I14 is lifted and forces the shoe up against the punches I4. Such upward movement of the shoe is limited by contact of the screw 32 in the stem 26 with the block I2 at the upper end of the slot 34, as illustrated in Fig. 6. It will be understood that the pressure of the gages on the shoe is such as readily to permit the upward movement of the shoe to take place. Patentable novelty involved in the above-described means for operating the valve I96 is claimed in a copending application of mine for Letters Patent for improvements in Machine for use in the manufacture of shoes, Serial No. 377,347, filed on February 4, 1941.

As further illustrated in Fig. 6, the upward movement of the stem 26 which results from the above-described upward movement of the shoe lifts the front end of the pawl I68 and thereby causes its rear end to release the plunger I64, so that the spring I68 opens the switch I 58. This results in breaking the circuit through the solenoid I50, thereby permitting the spring I i-8 to return the valve I36 to its initial position and thus to open the cylinder I06 to exhaust. The springs 80 and 16 then operate to return the side gages 42 and 44 to their initial positions and also to impart return movement to the bellcrank lever 88. In response to such movement of the bell-crank lever the lever I98 is returned to its initial position where it is held by the latch 2I8, thereby returning the valve I98 and opening the cylinder I18 to exhaust, so that the toe rest I15 is moved downwardly away from the shoe by gravity.

The manner of operation of the machine will now be briefly summarized. Since the machine is designed to operate on insoles mounted on lasts, such an insole will have been mounted on its last and preferably fastened thereto, as by temporary tacks, in the customary manner; and an upper also may have been assembled on the last and partially shaped thereover, especially if it is desired to determine the locations of the holes in the insole by reference to the outer face of the upper. As herein illustrated by way of example, such an upper has been subjected to the usual pulling-over operation and has also been lasted along its sides rearwardly of its toe portion before the shoe is presented to the machine. In presenting the shoe the operator engages the bottom face of the toe end of the insole with the shoe rest member 28 and the toe-end face of the upper with the end gage 36, as illustrated in Fig. l, the toe end of the shoe being spaced somewhat above the toe rest I14. At this time the side gages 42 and 44 are sufficiently retracted to facilitate movement of the shoe into position between them and to prevent any substantial rubbing of the straps 64 on the sides of the upper. By pressure of the shoe against the end gage 88 this gage is then moved rearwardly to the position idetermined by the stop screw 48, as shown in Fig. 5, and as a result of this movement of the gage the switch I58 is operated to energize the solenoid I50. By the action of the solenoid the valve I 36 is moved into position to admit compressed air to the cylinder I06, whereupon the piston I04 is moved downwardly to the posi- 1 tion determined by the stop screw II4. By the downward movement of this piston the bellcrank lever 88 is operated to swing the side gages 42 and 44 inwardly toward each other and to cause them to position the shoe laterally and angularly in proper relation to the punches I4. By the same movement of the piston I04 the spring 2| 4 is compressed and then the latch 2I6 is operated to release the lever I98 to the action of the spring, whereupon the lever is operated by the spring to move the valve I98 into position to admit compressed air to the cylinder I18. By the action of the piston I16 the toe rest I14 is then moved upwardly against the toe end of the shoe and imparts upward movement to the shoe to cause the punches I4 to punch the holes in the insole, as shown in Fig. 6, the upward movement of the shoe being limited by the shoe rest member 28 which moves upwardly only as far as permitted by the screw 32 and the slot 34. In this insole-punching operation the two punches I4 are controlled by the equalizing lever 20 which permits them to adjust themselves to the contour of the bottom of the last and causes them thereafter to act with substantially equal forces to punch the holes part way through the insole. The holes thus formed are shown at b in Fig. 8. In response to the upward movement of the shoe rest member 28 the pawl I88 is swung into position to release the plunger I84, as shown in Fig. 6, whereupon the spring I86 moves this plunger reversely to open the switch I58 and thus to de-energize the solenoid I58. The spring I48 then returns the valve I38 to its initial position, releasing the compressed air from the cylinder I06. By the action of the springs 60 and 16 the side gages are then returned to their initial positions and the bell-crank lever 88 is operated to return the piston I04 and also to return the lever I98 into the position where it is held by the latch 2I6. Such return movement of the lever I98 returns the valve I98, thus releasing the compressed air from the cylinder I18 and permitting the toe rest I14 to be moved downwardly by gravity. The operator then removes the shoe, whereupon the shoe rest member 28 and the end gage 35 are returned by the springs which control them, the pawl I68 resuming its initial relation to the plunger I84.
